Configuration of the LTMR PROFIBUS DP Network Port

Communication Parameters

Use the TeSys T DTM or the HMI to configure the following PROFIBUS DP communication parameters:

Network port address setting
Network port baud rate setting
Configuration channel setting

Setting the Node-ID

The Node-ID is the address of the module on the PROFIBUS DP bus. You can assign an address from 1 to 125. The factory setting for the address is 126.

You must set the Node-ID before any communication can begin. Use the TeSys T DTM or the HMI to configure the communication parameter Network Port Address Setting.

NOTE: Address 0 is an invalid value and is not permitted. A return to factory settings command sets the Node-ID to the invalid value 126.

Setting the Baud Rate

Set the baud rate to the only possible speed: 65,535 = Autobaud.

Use the TeSys T DTM or the HMI to configure the communication parameter Network Port Baud Rate Setting.

The factory setting for the Network Port Baud Rate Setting parameter is Autobaud (0xFFFF). Using Autobaud, the LTMR controller adapts its baud rate to that of the primary.

Setting the Configuration Channel

The LTMR configuration can be managed:

Locally through the HMI port using the TeSys T DTM or the HMI
Remotely through the network.

To manage the configuration locally, the Config via Network Port Enable parameter must be disabled to prevent an overwrite of the configuration through the network.

To manage the configuration remotely, the Config via Network Port Enable parameter must be enabled (factory setting).
